AGGRCOW - Aggressive cows
Farmer John has built a new long barn, with N (2 <= N <= 100,000)
stalls. The stalls are located along a straight line at positions
x1,...,xN (0 <= xi <= 1,000,000,000).
His C (2 <= C <= N) cows don't like this barn layout and become aggressive towards each other once put into a stall. To prevent the cows from hurting each other, FJ wants to assign the cows to the stalls, such that the minimum distance between any two of them is as large as possible. What is the largest minimum distance?
t – the number of test cases, then t test cases follows.
* Line 1: Two space-separated integers: N and C
* Lines 2..N+1: Line i+1 contains an integer stall location, xi
For each test case output one integer: the largest minimum distance.
1 5 3 1 2 8 4 9
FJ can put his 3 cows in the stalls at positions 1, 4 and 8,
resulting in a minimum distance of 3.

Very interesting problem , classic .
>.> You need to be bit lucky for the greedy approach to strike. Took me a whole day.
Where can i find solution of the problem
AC in one go
AC in one go !!!
AC in one go! Good question but sample test case could've been better.
Test cases are not up to mark showing correct answer even if coded wrong
Finally One Correct in One Go!!
